The influence of strabismus surgery on the blood-aqueous barrier: tyndallometry case studies in patients with risk factors.
We present tyndallometry as a method for investigation of subclinical changes in anterior-chamber flare in patients with risk factors regarding anterior-segment ischemia after squint surgery. The cases of six adult patients who underwent surgery on the vertical recti and who had additional risk either because of dysthyroid orbitopathy or because of transpositions carried out on the recti are presented. In one case a transient subclinical increase in the flare value was observed. This noninvasive method seems suitable for the provision of further information on the pathophysiology of anterior-segment ischemia and for monitoring of patients at special risk postoperatively such that early treatment can be started if necessary. Additionally, early detection of nonischemic intraocular inflammation in the postoperative course is rendered possible by this examination.
